4 Year-End Tax Planning Strategies for Open Enrollment

4 Year-End Tax Planning Strategies for Open Enrollment

September 15, 2025

As leaves begin to change and the fourth quarter approaches, there's more than just seasonal transitions on the horizon. October brings open enrollment season, the annual window when you can update your employee benefits. What most people don’t realize that open enrollment isn't just about choosing health insurance. It's actually one of the best opportunities of the year to optimize your entire financial strategy and reduce your tax burden.

Here are four key areas to focus on during this critical planning period.

Maximize Your Retirement Contributions

With only a few months left in the year, now is the time to see if you're making the most of your retirement savings opportunities. Review:

  • 401(k) contributions: Are you on track to hit the 2025 contribution limit of $23,500 (or $31,000 if you're 50 or older)? If not, consider increasing your contribution percentage for the remaining months of the year.
  • Investment allocation: When was the last time you reviewed how your retirement funds are invested? Market changes throughout the year may have shifted your allocation away from your target mix.
  • Employer matching: Double-check that you're contributing enough to receive your full employer match. It's essentially free money that you don't want to leave on the table.

For business owners, remember that if you want to establish a new retirement plan for your company, you need to have it set up and operational by October 1st, with 401(k) paperwork typically completed in October for a January start date.

Reassess Your Life Insurance Needs

Life changes happen throughout the year – promotions, new babies, home purchases, or changes in family circumstances. October's open enrollment is the perfect time to evaluate whether your current life insurance coverage still meets your family's needs.

Consider these questions:

  • Has your income increased significantly this year?
  • Do you have new dependents or changed family responsibilities?
  • Have you taken on new debt like a mortgage or business loan?
  • Are you approaching retirement and need less coverage, or do you need more to protect your spouse?

Many employer plans offer the option to increase coverage during open enrollment without medical underwriting, making this an ideal time to adjust your protection.

Take Advantage of Tax-Deductible Benefits

Open enrollment offers several opportunities to reduce your taxable income through pre-tax benefit elections:

Health Savings Accounts (HSAs): If you're eligible for an HSA through a high-deductible health plan, this is one of the most powerful tax-advantaged accounts available. Contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses are never taxed.

Flexible Spending Accounts (FSAs): While you typically need to use FSA funds within the plan year, they can provide valuable tax savings for predictable healthcare or dependent care expenses.

Other pre-tax benefits: Don't overlook options like commuter benefits, group legal plans, or other voluntary benefits that can be paid for with pre-tax dollars.

Business Owners: Year-End Planning Opportunities

If you're a business owner, the fourth quarter presents unique planning opportunities:

Retirement plan establishment: This is your last chance to set up a new retirement plan for your business and potentially make significant tax-deductible contributions for the current year.

Plan transitions: If you're considering switching from one type of retirement plan to another (like moving from a SEP-IRA to a 401(k)), October planning ensures everything is ready for the new year.

Business expense planning: Review your year-to-date business expenses and consider any equipment purchases, professional development, or other business investments that could provide tax benefits if completed before year-end.
